BACKGROUND Technical Field

The embodiments herein generally relate to location assignment, and more particularly, to an automatic system and method for adaptive location assignment to internet protocol (IP) indexed data streams using machine learning from partially observable data streams that are indexed with both network address and location information.

Description of the Related Art

Many modern data streams of entity activity are generated today such as people on applications, wearable devices, internet of things (IOT), logistic systems, connected cars, and like carry time indicator and public internet protocol (IP) address (to which the devices are connected) along with other payload data. Some data streams may carry explicit geolocation data such as latitude and longitude data if an onboard global positioning system (GPS) is available else no location information is provided. Alternatively, even if location information can be provided, such location information may be removed due to privacy requirements either by an individual or an entity owner. Typically, public IPs which constitute end-points in several exemplary scenarios are associated with a particular geo location (latitude, longitude). As per allocation of IPs on country-basis by internet corporation for assigned names and numbers (ICANN), the public IPs are either static or dynamic (ephemeral) depending on the underlying infrastructure used to implement the network. Real world geolocation of an entity is an essential factor to engage with the entity in terms of services, goods, and media contents and the like. Also, assigning location information to event streams that do not have location information improves the spatio-temporal density of the event streams in the context of a particular point-of-interest, an individual, and the like. Such improvement enables a) better model development to infer properties of the location based on data, b) in context of marketing provides better marketing spend to return on investment (ROI), c) offline attribution measurement in marketing.

Some of the existing approaches employ geolocation estimation techniques to identify entity location based on available location data. Also, several existing approaches train a machine learning model or a regression model with data streams that include network address and a corresponding geolocation to predict geolocation of an entity from the network address. However public IP allocation itself may be dynamic based on the underlying network especially if it is a mobile network. The public IPs for a mobile phone may be highly dynamic depending on the underlying carrier network and may be ephemeral as the public IPs are re-allocated dynamically. Furthermore, the ephemeral IPs could be located geographically anywhere within a network of a service provider and need not be geographically co-located. The above mentioned facts associated with the public IPs add complexity to the process of location estimation. Hence IP to location mapping needs to be constantly updated via incoming data streams and other application-layer approaches for inferring location. Due to partial visibility of incoming data streams from third party sources, constant updating of IP to location mapping is a complex process. Sometimes, the data sources, as observed, switch on and off for several reasons, such as, for example, outages, hardware failure, software failure, network failure, no network access, endpoint failure, intermediaries in the flow, corrupted events, blocked events, dropped events, lost event, user shutdown device and the like. For instance, data flow may be interrupted in airports or during prime hours when a major event is ongoing. Hence, the data may not be received in some regions/areas or time windows. Further, multiple sources of data overlap leading to duplicate event/entity counts—as the same people are recorded as they move around within regions, within countries, across countries. Further, some of the data sources have to be paid for and some of the data sources may not be accessible. In several exemplary scenarios, data may also be protected for maintaining privacy in some countries and consequently, only partial data may be available on a daily basis. Hence based on the partial data, building location context may only be possible up to about 30%.

Moreover, the existing techniques of estimating location for an entity utilize self-disclosed or initially collected IP (that remains static) to location data for estimating geolocation of the network address and are not scalable, are very difficult to bootstrap, and may not be adaptive for dynamic IPs.

Further, the processing of human mobility data points in a real-world environment may have multiple requirements, as for example, scalability, robustness, ability to deal with uncertainty (partial data), and since a single user may use multiple devices such as phone, television, personal computer engaged with a plurality of applications. In several exemplary scenarios, there may be a need to only sample a portion of data to process high throughput data streams under time and resource constraints for scalability. The data may be contextually relevant for a short time period.

Several techniques exist for processing of human mobility data points for multiple data streams that are controlled by a common entity, however, it may be quite a complex process for merging data streams from independently controlled data sources. In this scenario, a single IP may have multiple locations and a single location may have multiple IPs, since different internet service providers use different IPs for the same location. Also, due to large scale of data from multiple sources and partial visibility of data it may be difficult to manually perform the location estimation as a standalone function.

Accordingly, there remains a need for a system and method for mitigating and/or overcoming drawbacks associated with current systems.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.

As mentioned, there remains a need for a system and method for adaptive location assignment to internet protocol (IP) indexed data streams using machine learning from partially observable data streams. The embodiments herein achieve this by proposing an adaptive location assignment system that estimates real-time location for IP indexed data streams based on machine learning from partially observable data streams that are indexed with a network address and/or a location information. Referring now to the drawings, and more particularly to FIGS. 1 through 9, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.

The term “independently controlled data sources” refers to any source that may control or standardize different aspects of data streams. The different aspects include, but is not limited to, 1) the type of data that needs to be collected, 2) a time and location, the data needs to be collected, 3) data collection method, 4) modification of collected data, 5) portion of data to be revealed to public, 6) portion of data to be protected, 7) portion of data can be permitted by a consumer/user of the application/device, and 8) portion of data to be completely private.

A single real-world event may be tracked by different independently controlled data sources. Alternatively, data from the different independently controlled data sources may be interleaved to understand an event or sequence of events. For example, consider a consumer using multiple applications on his android phone, as he/she interacts with each application, multiple independent streams of events are produced since, each application being an independent source. Events and users may have different identifiers across different applications depending on how the application is implemented. Additionally, if one were to monitor the network, each application level event may generate additional lower level network events.

The term “partial observable data or partial data” refers to a data stream where all the events are not captured due to several reasons.

In an exemplary embodiment, the various modules described herein and illustrated in the figures are embodied as hardware-enabled modules and may be configured as a plurality of overlapping or independent electronic circuits, devices, and discrete elements packaged onto a circuit board to provide data and signal processing functionality within a computer. An example might be a comparator, inverter, or flip-flop, which could include a plurality of transistors and other supporting devices and circuit elements. The modules that are configured with electronic circuits process computer logic instructions capable of providing digital and/or analog signals for performing various functions as described herein.

FIG. 1 illustrates a system view 100 for estimation of location of internet protocol (IP)-indexed data streams, to some embodiments herein. The system view 100 includes one or more independently controlled data sources 104A-N, a network 106 and an adaptive location assignment system 108.

In some embodiments, the adaptive location assignment system 108 displays the estimated real-time location for the IP indexed data streams in an interactive user interface. In some embodiments, the adaptive location assignment system 108 displays the estimated real-time location for the IP indexed data streams over a map in the interactive user interface.

FIG. 2 is a block diagram of an adaptive location assignment system 108 for estimating location of internet protocol (IP)-indexed data streams, according to some embodiments herein. The adaptive location assignment system 108 includes an IP to Location map generator 202, a data structure 204, and an IP to Location estimator 206. The adaptive location assignment system 108 includes a memory to store set of instructions and a processor that is configured to execute the set of instructions to perform one or more actions related to real-time location assignment to IP indexed data streams. The IP to Location map generator 202 generates a base map by mapping IP addresses to corresponding locations at multiple levels of resolution based on historical data streams. In some embodiments, the IP to Location map generator 202 receives the historical data streams from one or more third party data sources. In some embodiments, the one or more third party data sources include, but is not limited to Xmode®, Cuebiq®, and similar other vendors. In some embodiments, the historical data streams include IP addresses along with latitude and longitude information sourced from geo-location to IP vendors. In some embodiments, the IP to Location map generator 202 generates the base map by mapping IP addresses to corresponding locations at country, state, city, and the like. In some embodiments, the base map provides a series of IPs on a trajectory of travel spanning wide regions potentially. In some embodiments, the base map includes both static and dynamic IP.

The IP to Location map generator 202 obtains, in real time, one or more location indexed data streams of entity activities from one or more independently controlled data sources. In some embodiments, the one or more location indexed data streams of entity activities is partially observable data. In some embodiments, the one or more location indexed data streams partially characterizes an activity of at least one entity. In some embodiments, the one or more independently controlled data sources 104A-N includes any network enabled device. In some embodiments, any network enabled device includes, but is not limited to, a mobile device, a smart phone, a personal digital assistant (PDA), a notebook, a global positioning system (GPS) device, wearable device, connected cars, logistics system, and the like. In some embodiments, the one or more location indexed data streams of entity activities includes, but not limited to, (i) location pings from one or more application engaged on the one or more entity devices, (ii) access pings from wireless hot-spots, (iii) active subscriber's data and location in different geo-spatial areas from the mobile network, and (iv) local information from traffic sensors or a public closed-circuit television (CCTV) camera for security and others. In some embodiments, the one or more location indexed data streams of entity activities include self-disclosed location information on a global website. In some embodiments, the entity activities include user activities. In some embodiments, the one or more location indexed data streams include an IP address, a spatio-temporal information and at least one entity identifier. In some embodiments, the entity identifier includes at least one of (i) an advertisement identifier (AdID), (ii) a cookie identifier (C) or (iii) a device identifier. In some embodiments, the spatio-temporal information includes a location data, and a time stamp data. The location data includes, latitude data, and/or longitude data. In some embodiments, the spatio-temporal information is either true GPS or a mapping provided by the advertisement exchange.

In some embodiments, the adaptive location assignment system 108 is communicatively coupled with a unifier that links one or more entity identifiers associated with one or more data streams to generate a unique entity identifier for an entity. The unifier may include, a clustering device, a disambiguator and a validator. The clustering device receives the one or more data streams and clusters the one or more entity devices by identifying entity devices having an association with each other with respect to at least one of an internet protocol (IP) address, a real-time event, a period of time or a location. The disambiguator analyses the clusters obtained from the clustering device and identifies sub-clusters that resolve to a single entity. The validator validates the single entity owns all the devices that exist in the sub-cluster against entity behavioral attributes and generates a unique entity identifier which corresponds to the single entity. In some embodiments, the unique entity identifier is also mapped to a home location of the single entity which enables the persistence of the unique entity identifier compared to traditional anonymized identifiers.

In an exemplary embodiment, John owns five devices. The incoming data streams from the five devices of John include five identifiers namely C1, C2, P1, P2, and T1 along with other payload information. The clustering device clusters the five identifiers namely C1, C2, P1, P2, and T1 based on at least one of the internet protocol (IP) address, real-time event, a period of time or a location. The disambiguator links these five identifiers and maps the unique user identifier “9517ANR”. Further, the disambiguator discerns patterns of identifiers that appear to always be “on the move” together and validates behavior signals from various identifiers in order to generate the unique entity identifier “9517ANR”. The behavioral attributes that are associated with all the individual identifiers may include male, 26-35, business professional, fitness freak, affluent, gamer, loves soccer and/or tennis. The disambiguator analyses the available clusters and begins to disambiguate or discern patterns of identifiers that are observed to always be together in spatio-temporal occurrences.

In an exemplary embodiment, a unique entity identifier “1001” has categorical attributes known to be a male, has a mobile identifier “1001_m” and has a plurality of cookie identifiers namely “1001_c_1”, “1001_c_2”, “1001_c_3” associated with it. The validator validates which cookies truly map to this mobile identifier “1001_m”. The above set of identifiers is generated from 3 candidate pairs which are a union of (1001_m,1001_c_1), (1001_m, 1001_c_2) and (1001_m, 1001_c_3). The validator runs an engagement activity that targets a male segment for which the unique entity identifier “1001” is a member. Further, the validator runs an engagement activity on mobile device identifiers which include targeting the unique entity identifier 1001_m and also a cookie engagement activity consisting of all the cookies that are linked with the unique entity identifier “1001”. The validator may validate if engagement is received for both the mobile identifier “1001_m” and set of cookies identifiers, it is validated that they both refer to the same individual.

In some embodiments, the adaptive location assignment system 108 is communicatively coupled with an event classifier that classifies a unified entity event from the one or more of data streams along with dynamic user attributes retrieved from a distributed memory store. In some embodiments, the unified entity event includes the values of the entity attributes.

The IP to location map generator 202 (i) generates an IP to location map (NM1) and a location to IP map (NM2) by mapping each network address associated with the one or more location indexed data streams to the corresponding locations of the at least one entity temporally and vice-versa, in the base map; and (ii) captures number of unique entity identifiers that are traversed on the IP addresses and time of traversal of the unique entity identifiers. In some embodiments, the IP to Location map generator 202 extrapolates data points in the partially observable data to estimate missed location data on time series and adds estimated location to the IPs to fill in time-gaps. In some embodiments, the IP to location map generator 202 generates the NM1 and the NM2 using the one or more location indexed data streams after filling the gaps in the location time series. In some embodiments, the IP to location map generator 202 updates the NM1 and the NM2 using the one or more location indexed data streams after filling the gaps in the location time series.

In some embodiments, the IP to Location map generator 202 extrapolates to fill gaps in the one or more location indexed data streams based on historical entity activities. An exemplary NM1 500A is provided in FIG. 5A. An exemplary NM2 500B is provided in FIG. 5B. It is noted that, FIG. 5A and FIG. 5B herein are provided for the purpose illustration and do not limit the scope of the invention. In some embodiments, a single IP may map to multiple locations that could be at different resolutions. In some embodiments, a single location may map to multiple IPs. In some embodiments, a static IP maps to a single location. In some embodiments, a dynamic IP maps to multiple locations. In some embodiments, the IP to Location map generator 202 generates the NM1 by mapping IP addresses from the one or more location indexed data streams to corresponding location temporally in the base map. In some embodiments, the IP to Location map generator 202 generates the NM2 by mapping location information from the one or more location indexed data streams to corresponding IP addresses temporally in the base map

The IP to Location map generator 202 performs scoring and ranking for each entry in the NM1 and the NM2 based on frequency of use of the IP address, and number of unique entity identifiers per IP address or per location. In some embodiments, the IP to Location map generator 202 generates an IP-to-IP graph that shows one or more IPs that are potentially linked to each other. The IP-to-IP graph also captures IPs that are static and IPs that are dynamic, including one or more metrics on a number of unique entity identifiers that traverse an edge and a time for traversal of a respective edge.

The IP to Location map generator 202 classifies each IP addresses into static or dynamic IP address in the NM1 and the NM2 based on the scoring and ranking of each entry. The IP to Location map generator 202 filters each entry in the NM1 and NM2 to generate a dynamic IP to location map based on a scoring and a ranking of each of the entries and a classification of IP addresses. In some embodiments, the IP to Location map generator 202 analyzes and filters both entries of single IP with multiple locations and entries of single location with multiple IPs based on the scoring and the ranking of each entry and the classification of each entry. In some embodiments, expiry of entries in the NM1 and the NM2 depends on a frequency of use, a number of users per IP or per location.

In some embodiments, the IP to Location map generator 202 updates the NM1 and the NM2 when a new set of data streams arrives to the adaptive location assignment system 108 with Bayesian updating technique using Kalman filter.

In some embodiments, the adaptive location assignment system 108 includes an active spatio-temporal (ST) region estimator. The active ST region estimator identifies active ST region for each entity associated with IP address based on the one or more location indexed data streams. In some embodiments, for each unique entity identifier received, the active ST region estimator maintains the tuple—timepoint, IP, location along with the last known true location that is received via GPS. For every user or entity, the active ST region estimator maintains the last known location. An exemplary entity location table 500C that maintains last known entity location is provided in FIG. 5C. FIG. 5C herein are provided for the purpose illustration and do not limit the scope of the invention. In an exemplary scenario, if at any point in time, a user or an entity is at a physical location and cannot move to another location such as greater than 25-30 miles (depending on a mode of travel) within such as a 1 min to 5 min duration, all the pings from the user or entity must be clustered within a spatio-temporal region called an active ST region. When the user or entity engages with a set of applications and a browser on a mobile device at a point in time, an active ST region estimator receives a series of location pings interspersed with non-location pings in application, in the browser, in AdId and the cookie-based traffic. The active ST region estimator 1) assigns to all the IPs, one or more corresponding nearby locations, b) assigns to all non-location pings (either AdID or cookie)—a most frequent location in the active ST region in the time window. In some embodiments, the active ST region estimator generates a table with a last known location for the user or the entity.

The data structure 204 stores the base map, the NM1 and the NM2, the dynamic IP to Location map and the table with last known location for the user or the entity that are automatically updated when a new set of data streams arrive to the adaptive location assignment system 108. In some embodiments, the NM1 and the NM2 are represented in the form of a hyper cube that is spatially partitioned with geo hashes in terms of a key value data structure for each geo location. In some embodiments, the hyper-cube includes heterogeneous collection of geo hashes. In some embodiments, the hyper-cube includes a combination of geo hashes at granularity. In some embodiments, the key value data structure is a hyper log log (HLL) data structure. In some embodiments, the key value data structure is maintained temporally on per day basis, per hour basis, or in a rolling 30-day window. In exemplary embodiment, a country is represented by 1×10⁶ HLLs in the hyper-cube that maintains a million keys for every day (similar for every 4-hour window). For example, for a 30-day period, the key value data structure maintains 30 million keys. In some embodiments, the dynamic IP to Location map is represented in a form of hyper cube. In some embodiments, the table with last known location for the user or the entity is represented in a form of hyper cube.

The IP to Location estimator 206 estimates a real-time location for an IP indexed data streams at multiple levels of resolutions based on the dynamic IP to location map and the active ST region of each entity. In some embodiments, the IP to Location estimator 206 uses Kalman filtering techniques on a per user or entity basis for location estimation. In some embodiments, the IP to Location estimator 206 uses land use and land type information for location estimation. For example, while considering at least two data streams that includes a location-indexed stream (LI) and a stream with IP for whom location needs to be assigned (LA), a user or an entity current position is the sum of LA+LI+error (error in estimation (LA) and due to device error, external error due to blocking of GPS etc. in LI). Kalman filters are well-understood techniques for state estimation given the previous position in dynamic systems.

In some embodiments, the IP to Location estimator 206 uses Kalman filter to estimate the next position of a user or an entity within a reasonable time interval like 10 to 30 minutes depending on where the user or the entity is located like at home, versus a shopping district etc. The Kalman filter implementation follows standard techniques plus heuristics. In some embodiments, the IP to Location estimator 206 uses the land-use pattern of the current location like residential areas vs business district vs farmland etc. to estimate the next position of the user or the entity.

In some embodiments. IP to Location estimator 206 is embedded with a machine learning model. In some embodiments, the machine learning model is trained with real-time location and IP indexed data streams along with the active ST region of each entity to receive an input query includes an IP address and to output real-time location information associated with IP address received. In some embodiments, the machine learning model is trained with the base map, the dynamic IP to location map and the table with last known location for the user or the entity.

In some embodiments, the IP to Location estimator 206 is executed on offline mode. In some embodiments, the IP to Location estimator 206 is refreshed periodically. In some embodiments, the IP to Location estimator 206 is refreshed every 24 hours.

In some embodiments, the estimated location for IP indexed data streams is used for evaluating visit histories per unique entity identifier, and an offline attribution per unique entity identifier for a region of interest (ROI) based on estimated location for a non-location indexed data event.

In some embodiments, a media content is transmitted to entity devices associated with the ROI when visit histories per unique entity identifier, and an offline attribution per unique entity identifier is high for the ROI. In some embodiments, an output of the IP to location estimator 206 is used for fraud detection and filtering out a lot of noisy traffic, unstable applications, and the like.

The adaptive location assignment system 108 enables the practical application of hyper-local campaigns to non-location traffic that in turn improves several aspects of campaign delivery. Location attribution may also improve offline attribution, and thereby potentially improve dwell time measures and consequently also de-risk dependence on only location traffic whose scale is reduced due to tightening privacy needs in many markets.

FIG. 4A illustrates an exemplary trajectory image 400A that is generated based on location indexed data stream associated with a first entity from a first independently controlled data source. FIG. 4B illustrates an exemplary trajectory image 400B that is generated based on a location indexed data stream associated with the first entity from a second independently controlled data source. The trajectory image in the FIGS. 4A and 4B show that there is partial observability and a gap in the location indexed data stream. The gap in the trajectory of the entity happens due to a partial data that includes a location data not observed when GPS times out or the user switches off the GPS.

In some embodiments, the IP to location map generator 202 extrapolates data points in the partial data to estimate missed location data on time series and adds estimated location to the IPs to fill in time-gaps. For example, if a person is on the road before the gap, the same person should be on the road for the rest of the time after the gap. The IP to Location map generator 202 generates the NM1 and the NM2 using the one or more location indexed data streams after filling the gaps in the location time series. In some embodiments, the IP to location map generator 202 updates the NM1 and the NM2 using the one or more location indexed data streams after filling the gaps in the location time series.

In some embodiments, the IP to Location map generator 202 analyzes and filters both entries of single IP with multiple locations and entries of single location with multiple IPs based on the scoring and the ranking of each entry and the classification of each entry. In some embodiments, expiry of entries in the NM1 and the NM2 depends on a frequency of use, a number of users per IP or per location.

In some embodiments, the IP to Location map generator 202 updates the NM1 and the NM2 when a new set of data streams arrives to the adaptive location assignment system 108 with Bayesian updating technique using Kalman filter.

In some embodiments, the adaptive location assignment system 108 includes an active spatio-temporal (ST) region estimator. The active ST region estimator identifies active ST region for each entity associated with IP address based on the one or more location indexed data streams. In some embodiments, for each unique entity identifier received, the active ST region estimator maintains the tuple—timepoint, IP, location along with the last known true location that is received via GPS. For every user or entity, the active ST region estimator maintains the last known location. An exemplary entity location table 500C that maintains last known entity location is provided in FIG. 5C. FIG. 5C herein are provided for the purpose illustration and do not limit the scope of the invention. In an exemplary scenario, if at any point in time, a user or an entity is at a physical location and cannot move to another location such as greater than 25-30 miles (depending on a mode of travel) within such as a 1 min to 5 min duration, all the pings from the user or entity must be clustered within a spatio-temporal region called an active ST region. When the user or entity engages with a set of applications and a browser on a mobile device at a point in time, an active ST region estimator receives a series of location pings interspersed with non-location pings in application, in the browser, in AdId and the cookie-based traffic. The active ST region estimator 1) assigns to all the IPs, one or more corresponding nearby locations, b) assigns to all non-location pings (either AdID or cookie)—a most frequent location in the active ST region in the time window. In some embodiments, the active ST region estimator generates a table with a last known location for the user or the entity.
